Multi-handled sealed bag

ABSTRACT

A sealed multi-handled bag is provided that includes a first handle at a first end and a second handle at a second end. In one embodiment, the handles are on substantially opposite ends of the bag. The sealed bag may be made from plastic and may contain loose materials, such as a salt. In some embodiments, one or more of the handles are formed from heat-sealed layers of bag material having a grip cut therein. A method for filling and sealing the multi-handled sealed bag includes filling a bag having a first closed end through a second open end, and sealing the second open end to form a handle. In one embodiment, sealing the second open end includes heat-sealing opposing layers of bag material together and cutting a handle through the layers. In another embodiment, the method includes folding-over the layers of bag material.

TECHNICAL FIELD

This invention relates generally to a multi-handled sealed bag. Moreparticularly, the invention concerns a sealed loose-materials bag, suchas a salt bag, having two or more handles and a method for filling andsealing such a bag.

BACKGROUND

There are many different types of sealed bags used for various purposes.One type includes moderate to heavy-duty sealed bags used for packagingloose materials. Conventional bags of this type frequently have acapacity of around 10 pounds to 100 pounds or more. For instance,conventional heavy-duty sealed bags are often used to package chemicalssuch as salt or fertilizer, landscaping materials such as gravel orpotting soil, pet food, and the like. When filled with loose materials,these conventional bags may be difficult to carry without handles due tothe pliancy of the bag and the ability for the loose materials to shift.For example, when a user grabs such a bag along its body, the loosematerials contained therein may shift and thereby lessen the user'sgrip.

Many conventional sealed bags that package loose materials include ahandle on one end to improve a user's ability to grab the bag. Formoderate to heavy-duty bags, however, a single handle may be lessdesirable. For example, conventional paper or plastic heavy-duty bagshave a single handle formed from the bag material. These handles maystretch during use with heavier loads. Further, it may be difficult anduncomfortable for a user to carry these heavy bags using a singlehandle. Accordingly, a need exists for a moderate to heavy-dutyloose-materials bag having improved features for handling and carryingthe bag.

SUMMARY

In order to overcome the above-described disadvantages and otherdisadvantages that will become apparent when reading this specification,aspects of the present invention provide a multi-handled sealed bag.According to one aspect of the invention, the multi-handled sealed bagmay have a first handle on a substantially opposite end from a secondhandle. According to another aspect, the sealed bag may be made fromplastic and contain loose materials, such as a salt. One or more of thehandles may be formed from heat-sealed layers of bag material having ahandle cut therein according to a further aspect of the invention.

Aspects of the present invention further provide a method for fillingand sealing a multi-handled sealed bag that includes filling a baghaving a closed end through an open end, and sealing the open end toform a handle, Sealing the open end may include heat-sealing opposinglayers of bag material together and cutting a handle through the layers.Sealing the open end may also include sealing opposing layers of bagmaterial together near a pre-cut handle. The method may includefolding-over the layers of bag material to form a handle flap. Otheraspects of the invention provide a method for filling and sealing amulti-handled sealed bag that includes sealing a first end to form aflap and a handle in the flap, filling the bag through an oppositesecond end, sealing the second end, and attaching a rigid handle to thesecond end.

DETAILED DESCRIPTION OF THE FIGURES

The various aspects of the invention may be embodied in various forms.The following description of the figures shows by way of illustrationvarious embodiments in which aspects of the invention may be practiced.It is to be understood that other embodiments may be utilized andstructural and functional modifications may be made without departingfrom the scope of the present invention. Referring now to FIGS. 1-4, atwo-handled loose-material bag 10 according to an embodiment of theinvention is shown. As shown, bag 10 generally includes a body 12,loose-material 14 stored within body 12, a first handle 16 at a firstend, a second handle 18 at a second end generally opposite to the firstend, and a tear seam 20 formed in body 12.

Bag 10 may be made from a variety of materials, such as sheets 22 and 24of single-ply or multi-ply plastic. For example, sheets 22, 24 may besingle-ply polyolefin plastic sheets such as polyethylene orpolypropylene. The plastic sheets may have a thickness of about 3 to 12mils. Preferably, sheets 22, 24 have a thickness of about 5 to 10 mils,and even more preferably about 5.5 mils. Plastic sheets in these rangesprovide sufficient strength for heavy-duty packages, such as packagescontaining about 10 to 100 pounds of loose materials; although, plasticsheets in other ranges may be appropriate. Other sheet materials mayinclude woven and non-woven fabric, paper materials, sheets formed fromplastic and/or glass fibers, etc. Combinations of sheet materials arealso appropriate, such as paper sheets lined with plastic. Body 12 ispreferably formed from a tube of plastic material formed from sheets 22and 24 connected along their lateral sides, which are sealed at oppositeends. It may also be formed via other methods, such as by connectingopposing plastic sheets 22 and 24 on 4 sides.

Bag 10 is preferably made from plastic, which permits storage ofmoisture-sensitive materials. For instance, it may be desirable topackage salt, fertilizer, cement, granular chemicals, pet food,landscaping materials such as mulch, and similar moisture-sensitiveloose-materials in sealed plastic bag 10. The term loose-materials asused herein generally refers to free flowing materials, such as liquidsor granular materials that can be moist or dry. These bags may have acapacity to hold around 10 pounds to 100 pounds of loose-materials, andpreferably around 25 pounds to 60 pounds. As such, bag 10 may be usedfor moderate to heavy-duty applications.

Moderate to heavy-duty bags filled with loose-materials may be difficultto carry without a handle or with only a single handle. Because theloose-materials 14 stored therein are generally free flowing, when auser grabs bag 10 about its body 12, the bag conforms to the user'sgrip. Depending on how freely loose-materials 14 flow and how easily bag10 conforms to the user's grip, it may be difficult for the user to gripbody 12. Further, the user's grip may change as loose-materials 14continue to flow while bag 10 is being carried, which may degrade his orher grip.

Carrying hag 10 using a single handle 16 or 18 may be desirable incertain circumstances, such as for lightweight applications. However, inmany circumstances, such as when carrying heavier bags, using a singlehandle 16 or 18 may be less desirable. For example, the single handlemay stretch. Further, the concentration of force using a single handlemay be uncomfortable for the user. For instance, suppose a 100-pound bagformed from opposing layers of 5.5 mil thick plastic has a handle cutthrough sealed layers of the plastic. As such, the plastic in the handleregion may be 11 mils thick, or 0.011 of an inch. Suppose the handle isthree inches long. Without bunching, such a handle transmits over 3000p.s.i. of pressure to the user's hand. With reasonable bunching whencarrying the bag, the effective thickness of the handle may be aboutone-eight inch wide. As such, the handle transmits about 267 p.s.i. ofpressure to the user's hand.

Providing a pair of handles at opposite ends of bag 10 greatly reducesthe pressure applied to a user's hands. Simply using two handles reducesthe applied pressure in half, for example, to 133 p.s.i. using theexample above. When carrying bag 10 using handles at opposing ends thatare cut out of plastic material, such as handles according to thepresent embodiment, the pressure may be reduced further. This is due tothe increased width of material at the cutout handle that is applied tothe user's hands when the bag is substantially horizontal. When the bagis horizontally oriented, the user's hand contacts side portions of thehandle as well as the cutout portion. Using the example above, the widthof handle material applied to the user's hands may be about one-half aninch while carrying bag 10 in a substantially horizontal orientation. Assuch, the pressure applied to each hand when carrying a 100-pound bag isabout 33 p.s.i.—a reduction of 234 p.s.i. compared to a bag having asingle handle cut out of plastic sheet material.

Further, providing a pair of handles at opposing ends of bag 10 improvesthe user's ability to control moderate to heavy-duty bags. This isparticularly true when loose-materials are packaged that can shift orflow when bag 10 is carried. By positioning handles 16, 18 at oppositeends, a user has two points of contact with bag 10, which provides alarger degree of control over bag 10 compared to a single handle.

This may be particularly advantageous for salt bags, such as bagscontaining water conditioner salt, de-icing salt, and agricultural salt,For these bags, the user may need to maintain increased control of bag10 as the salt is poured from the bag. For instance, a user of bag 10containing de-icing salt will be able to better control the pour rateand spreading of de-icing salt over a driveway or sidewalk using thepair of handles 16 and 18 disposed at opposite ends. By controllingopposing ends of bag 10, the user can more easily control theorientation of bag 10 and thereby the flow rate of salt there from.

In another example, a salt bag having handles at opposite ends providesusers with more flexibility in dispensing the salt. For example, a tallfirst user may lift bag 10 using handle 16 opposite tear seam 20 toempty the contents (e.g., water-softener salt) into a desired container(e.g., water-softener unit) from the bottom of bag 10. A shorter seconduser may lift bag 10 using handle 18 near tear seam 20 to pour thecontents into a desired container from the top of bag 10.

In other variations, a plurality of handles may be placed at differentpositions along the exterior of the bag, which can provide the user witha variety of choices for carrying and handling bag 10. For example,placing a handle along each of the four edges of bag 10 could allow theuser to choose which pair of handles to use. Further, using two handlesreduces the stress on a user's hands compared with a single handle.

Handles 16 and 18 may be formed by sealing opposing sheets 22 and 24such that a length of material extends beyond seals 26 and 28 to formflaps 30 and 32. The width of flaps 30 and 32 may be about 2 to 4 incheswide, and is preferably about 2.5 to 3.5 inches wide. Depending on thematerial used for sheets 22 and 24, sheets 22 and 24 may be sealed viaan adhesive bond, a heat seal, a sewn seam, etc. When using plasticmaterial for sheets 22 and 24, the sheets are preferably sealed via aheat seal, which may be formed using a hot press, an ultrasonicheat-sealing process, a hot air sealing process, a hot band heatingprocess or similar methods.

Preferably, a second distal seal 42 and 44 may be formed at the distalends of flaps 30 and 32 to improve the connection between sheets 22 and24 in flaps 30 and 32. Improving the connection between sheets 22 and 24in the flap regions keeps the sheets from separating at the distal endsof the flaps. This provides improved handles 16, 18 formed in the flapsby ensuring a user engages both sheets 22 and 24 when grabbing eitherone of handle 16 and 18.

Seals 26 and 28 are preferably substantially permanent, non-resealablebonds. Using plastic or a similar substantially moisture-imperviousmaterial for sheets 22 and 24, combined with using substantiallypermanent bonds for seals 26 and 28, provides a large degree ofprotection to the loose materials 14 stored within bag 10. Substantiallypermanent bonds 26 and 28, such as formed via a heat sealing process,are highly impervious to air and moisture, which protects loosematerials 14 from such contact. Further, substantially permanent bonds26 and 28 provide a robust seal that is difficult to inadvertentlybreak, such as during shipping and handling. Thus, seals 26 and 28 arepreferably a substantially permanent bond, such as a heat seal bond or apermanent adhesive bond that provides a substantially impermeableattachment between sheets 22 and 24.

In order to reinforce the handles, a patch 34, 36 may optionally beplaced on one or both sides of flaps 30 and 32. Patches 34, 36 mayinclude a plastic material about 2 to 12 mils thick, and preferablyabout 5.5 mils thick. Patches 34 and 26 may be made from a plasticstrips, such as polyethylene, which are bonded respectively to flaps 30and 32. Patches 34 and 36 may be made from other materials, such asfibrous tape known as DUCT tape or TYVEK. Patches 34 and 36 may beadhered using various means, such as a heat bond, an adhesive, or aresin such as an epoxy or a hydrocarbon resin.

To form each handle 16 and 18, a series of perforations may be cutthrough the layers of material 30, 32 and patch 34, 36 to form a grip38, 40. Alternatively, the grip 38 and 40 may be formed from a singlecut. One or both of grips 38 and 40 may be cut through flaps 30 and 32after the flaps are formed and bag 10 is filled and sealed.Alternatively, grips 38 and 40 may be pre-cut in panels 22 and 24 priorto forming bag 10. Further, one or both of grips 38 and 40 may bepre-cut in unfilled bag 10. A cutout handle provides a simple andinexpensive handle that works well with a bag having handles at opposingends. This is because the vertical angle of the bag affects the width ofmaterial transmitting force to the user's hand. When using handles atopposite ends, bag 10 is generally oriented in a horizontal position,which greatly improves the amount of handle material transmitting forceto the user's hand.

As shown in FIGS. 1-4, tear seam 20 may be formed from a line ofperforations through sheets 22 and 24 and material 32 as disclosed inU.S. Pat. No. 6,402,379. The perforations may be punched or cut throughsheets 22 and 24. The perforations may be formed prior to forming bag 10as part of the process of forming bag 10, or after bag 10 is formed.Other breakout technologies may also be used, such as various other tearseam designs, tear-off end portions, pull-apart end seams, etc.

Referring now to FIGS. 5 and 6, a two-handled loose-material bag 110according to another embodiment of the invention is shown. Bag 110generally includes the aspects and preferences of bag 10, except aspertaining to the fold-over flap 130 discussed hereafter and the secondtear seam 21. As shown, bag 110 includes a first flap 32 formed asdiscussed in relation to bag 10. The second flap 130 is formed byfolding over end portions of sheets 22 and 24. The fold-over portionsare joined along seal 26 in the same manner discussed in relation to bag10. A grip 138 is cut through the double layers of material in flap 130to form handle 116. As with bag 10, grip 138 may be formed from acomplete cutout or a series of perforations. Further, as with bag 10,grip 138 may be cut after bag 110 is filled and sealed, or pre-cut priorto filling and sealing bag 110.

By doubling the layers of material in flap 130, a reinforced handled 116is provided. For example, if each sheet 22, 24 has a thickness of about5.5 mils, then flap 130 has an overall thickness of about 22 milscompared to 11 mils without the foldover. The thicker handle improvesstrength and reduces the amount of pressure applied to a user's hand.Bag 110 further includes a second tear seam 21 disposed proximate tohandle flap 130. Handles at opposite ends along with tear seams atopposite ends provide a user with flexibility in how to handle bag 110and dispense materials therefrom.

Referring now to FIGS. 7 and 8, a two-handled loose-material bag 210according to a further embodiment of the invention is shown. Bag 210generally includes the aspects and preferences of bag 10, except aspertains to the fold-over flaps 230 and 232 discussed hereafter. Asshown, bag 210 includes a pair of opposing fold-over flaps 230 and 232formed as discussed in relation to bag 110. In addition, patches 234 and236 may optionally be attached to flaps 230 and 232 respectively asdiscussed in relation to bag 10. As shown in FIG. 7, patches 234 and 236may be rounded or have other shapes as desired. As with previousembodiments, grips 238 and 240 are formed from a single cut or a seriesof perforations through the double layers of material in flaps 230 and232 and, if added, through patches 234 and 236 to form handle 116.Patches 234, 236 complement the folded-over material of flaps 230 and232 to further reinforce handles 216 and 218. However, the folded-overmaterial of flaps 230 and 232 may have sufficient strength without theaddition of patches 234 and 236.

Referring now to FIG. 9 along with FIGS. 1 and 14, a method 310 forforming a sealed multi-handle bag, such as bag 10, according to anembodiment of the invention is generally shown. According to method 310,an open bag is formed 312 that has a handle at a first sealed end. Usingbag 10 shown in FIG. 1 as an example, an open bag is generally formedfrom a tube of plastic material, which may include sheets 22 and 24connected along their lateral sides. The tube of plastic material may beformed from various methods, such as an extrusion process. In analternative arrangement, an open bag may be formed by sealing sheets 22and 24 to each other along three sides. A handle 18 may be formed at thefirst sealed end by sealing opposing sheets 22 and 24 to each other suchthat an end flap 32 is formed extending beyond seal 28. Preferably, seal28 is a double seal made up of a pair of substantially parallel sealsdisposed proximate to each other, which provide a higher strength and amore resilient bond between sheets 22 and 24 than a single seal. Adistal seal 44 along the end portions of flap 32 may further connectlayers of sheet material forming end flap 32. Distal seal 44 provides amore robust handle 16 by preventing sheet material in flap 32 from beingpulled apart.

Handle 18 may be formed by cutting one or more perforations 40 throughflap 32 in the shape of a desired grip. Other handle configurations arepossible, such as those discussed above along with bags 10, 110 and 210,which may include a reinforcing patch 36 or fold-over layers ofmaterial. Reinforcing patches 36, 38 may be added to the appropriateflap regions 30, 32 of sheets 22, 24 at various points in the process.For example, a patch 38 may be added to flap 30 after seal 28 is formed.In another example, patch 38 may be added after the open bag is formed312, and may be pre-cut with a single cut or perforations to matchhandle cut(s) 40 in flap 32. In a further example, patch 38 may bepre-applied to bag material prior to forming the open bag, and may bepre-cut via a single cut 40 or with a series of perforations.

In a preferred embodiment, the empty, open bag is filled and sealed viaa commercial packaging process 310. In such a commercial process, eachopen bag is vertically hung on a conveyer (not shown) in an openconfiguration with the open end oriented upwards and with the firstsealed end and handle 18 oriented downwards. The open bag is then filled314 with loose materials such as salt through the open end. Once filled,a handle flap 30 is formed 316 in the open end while sealing and closingthe open end.

FIG. 14 shows a heat-sealing station 50 for bag 10 according to apackaging embodiment of the invention, which illustrates an embodimentfor the sealing step 316 of method 310. As shown, opposing sheets 22 and24 are bonded to each other with a seal 26 such that additional materialextends beyond seal 26 to form handle flap 30. Preferably, the layers ofmaterial in flap 30 are also sealed to each other along their distalportions to form second distal seal 42. Excess material extending beyondsecond distal seal 42 may be trimmed via cutters 51 as needed. As shown,seal 26 and distal seal 42 are preferably formed substantiallysimultaneously.

In the commercial packaging system of which heat-sealing station 50 is apart, this may occur by compressing sheets 22 and 24 between a firstpair of opposing guides 52 at the location for seal 26, whilesubstantially simultaneously compressing sheets 22 and 24 between asecond pair 54 of opposing guides at the location for distal seal 42.While sheets 22 and 24 are compressed together, a first and second pairof opposing heat-bars 56 transfer heat to sheets 22 and 24 and therebyform seal 26. If a single seal were desired rather than a double seal,only first pair of opposing heat-bars would be used to form seal 26. Atsubstantially the same time, a third pair of opposing heat-bars 58transfers heat to sheets 22 and 24 to form distal seal 42. A pair ofopposing feed belts 60 advances bag 10 between the guides and heat-barsfor the sealing operation. An opposing pair of cooling tubes 62 chillsseals 26 and 42 as bag 10 advances past cooling tubes 62. As shown, thefilled bag is preferably hanging vertically during the sealing process,which keeps the loose materials from interfering with the seals.

Forming seals 26 and 42 at substantially the same time provides severaladvantages. It reduces the steps in the commercial process compared withseparate sealing steps for each seal, which saves production time andcosts. Further, compressing sheets 22 and 24 at the same time keepssheets 22 and 42 in a taut configuration in the area of flap 30, whichprovides an improved handle 16. In the event of a pre-cut handle,substantially simultaneous sealing the sheets together can provideimproved alignment between the pre-cut grip perforations 38 in eachsheet.

If handle 16 is not pre-cut, it may be formed by cutting 318 one or moregrip perforations 38 through flap 30 into the shape of a desired gripafter the heat-sealing operation. As mentioned above, handle 16 may alsobe formed by pre-cutting one or more perforations 38 through opposingsheets 22 and 24 prior to forming bag 10 or prior to filling and sealingbag 10. When pre-cut, handle 16 is formed from the pre-cut line orseries of perforations 38 as opposing sheets 22 and 24 are sealed toeach other to form flap 30. Other handle configurations are possible,such as those discussed above along with bags 10, 110 and 210, which mayinclude a reinforcing patch 38 or fold-over layers of material, or suchas the rigid handle discussed later along with bag 510.

Referring now to FIG. 10 along with FIGS. 5 and 6, a method 410 forforming a sealed multi-handled bag, such as bag 110, is generally shownaccording to another embodiment of the invention. Method 410 includesthe same aspects and preferences as method 310, except as relating tothe formation of handle 116 along with sealing the open end. As shown,end portions of opposing sheets 22 and 24 may be folded-over 415 to forma fold-over flap 130 as part of sealing the open end. As such, adouble-thick handle 116 is formed at the previously open end. Asdiscussed above with method 310, one or more patches may be added toeither or both of handle flaps 130 and 32. As also discussed above withmethod 310, one or more perforations 138 may be cut in flap 130 to formhandle 116. Alternatively, one or more perforations 138 may be pre-cutin opposing sheets 22 and 24 prior to forming bag 110 or prior tofilling and sealing bag 110. As with method 310, a distal seal (notshown) may also be formed in flap 130.

Referring now to FIGS. 11 and 12, a two-handled loose-material bag 510according to a further embodiment of the invention is shown. Bag 510generally includes the aspects and preferences of bag 10, except aspertains to the rigid handle 516 discussed hereafter. As shown, bag 510includes a rigid handle 516 at the first end and a flap 32 at theopposing second end with handle 18 formed therein as discussed inrelation to bag 10. As shown, handle 18 includes a single perforation 40cut to form the grip. As with previously discussed embodiments, theperforation may be cut through the sealed bag, pre-cut in sheet material22 and 24 prior to forming bag 510, or pre-cut in the unfilled bag.

Rigid handle 516 is a relatively stiff handle made from plastic, metalor a comparatively stiff material, which is attached to bag 510 at thefirst end. For example, rigid handle 516 may be an injection-moldedplastic handle that is bonded to heat seal 26 via a thermal bond, anadhesive bond, or a sewn attachment. Rigid handle 516 providesadvantages over handles formed through plastic sheets, such as handle 18formed in flap 32. For example, rigid handle 516 is comparatively easierto grab than handle 18 due its larger width, W and thickness, T, whichis particularly advantageous when used as a single handle to carry bag510. Consequently, when a user grabs bag 510 using rigid handle 516 as asingle handle, the force is spread out over a larger area and therebytransmits less pressure to the user's hand. Further, due to the stiffnature of rigid handle 516, it does not bunch-up around a user's hand,which avoids discomfort associated with pliant handles gathering arounda user's hand. In addition, rigid handle 516 may be stronger than handle18 and comparable handles, which may stretch or break more easily whenused as a single handle.

Referring now to FIG. 13 along with FIGS. 10 and 11, a method 610 forforming a sealed multi-handled bag, such as bag 510, is generally shownaccording to another embodiment of the invention. Method 610 generallyincludes the same aspects and preferences as method 310, except asrelating to the formation of handle 516. As shown, handle 18 is formedat the second end by sealing 612 opposing sheets 22 and 24 to each othersuch that end flap 32 is formed extending beyond seal 28. A distal seal44 along the end portions of flap 32 may further connect layers ofmaterial forming end flap 32.

Handle 18 may be formed by cutting 614 one or more perforations 40through flap 32 in the shape of a desired grip. Alternatively, one ormore perforations 40 may be pre-cut in opposing sheets 22 and 24, suchthat handle 18 is formed when sheets 22 and 24 are sealed to each otherto form flap 32. Other steps for forming handle 18 may also be used,such as those discussed above along with bags 10, 110 and 210, which mayinclude adding a reinforcing patch or folding-over layers of material.After the open bag is formed, bag 10 is filled 616 with loose materialssuch as salt through the open first end. Once filled, the first end issealed 618 to form seal 26. Rigid handle 516 is attached 620 to thefirst end by attaching it to seal 26 via a heat seal, an adhesive, amechanical attachment, and/or other attachment means.

While the present invention has been described in connection with theillustrated embodiments, it will be appreciated and understood thatmodifications may be made without departing from the true spirit andscope of the invention. In particular, the invention applies tolight-duty, moderate-duty and heavy-duty bags containing loose materialsas well as restrained materials. Further, the invention applies tovarious shapes and sizes of bags, and to a wide variety of handle types.
